Concerning the proposed subjects, computer simulations were done and the obtained results were presented in research meetings, Domestic conferences, and International conferences. Also their results were published as scientific papers in several journals. The summary of the results are as follows. Nonlinear dynamics in a neural network model are investigated by means of numerical simulations and a question whether the same dynamical properties is able to be described by rules of cellular automata or not., are discussed. The answer is affirmative and an example is actually shown in a specified case of 2-dimensional motion pictures provided one employs not 2-states-3-neighbors but many neighbors with totalistic rules. Numerical simulations were done and the successful results were reported in domestic conferences and in international conferences as well. Several papers were written by the investigators and a few were already published in a few journals. A third meeting was held with all the investigators together and the recent contents of each research activities were introduced and discussed.

关于所提出的主题，进行了计算机模拟，并在研究会议，国内会议和国际会议上介绍了所获得的结果。他们的研究结果也作为科学论文发表在几个期刊上。结果总结如下。通过数值模拟研究了神经网络模型中的非线性动力学，并讨论了同样的动力学性质是否可以用元胞自动机的规则来描述的问题。讨论了答案是肯定的，一个例子实际上是在一个指定的情况下，提供了一个2维的电影采用不2-状态-3-邻居，但许多邻居与整体的规则。进行了数值模拟，并在国内会议和国际会议上报告了成功的结果。研究人员撰写了几篇论文，其中一些已经发表在一些期刊上。第三次会议由所有研究人员共同举行，并介绍和讨论了各项研究活动的最新内容。
